While looking for yarn online, I came across Lion Brand yarn and signed up for their mailed catalog (beautiful, so well produced from a design and printing standpoint) and for their emailed newsletter. The newsletter is not long; it seems to come about once a week. What I appreciate about it is the free pattern that is highlighted in each issue.
A few months ago, the free pattern was for a crocheted Market Bag (Pattern #: 70221A). With patterns I like, I simply select with my cursor, then copy (CTRL C) and (after opening a new doc in MS Word) paste (CTRL V) the photo and directions into an MS Word document, then save (CTRL S) in a folder on my computer or print out (CTRL P) and put in a 3-ring binder (where I then have a pattern book filled with patterns I like and can actually use).
Lion also sells all the yarn needed for the bag, but as the organic yarn recommended came to ... gulp ... $45, I used another solution.
My results (the first photo here) looked VERY colorful. I wished I'd had more pink/blue to use intead of the weird green/turquoise mix on the handle. Like many a frustrated artist, I was sure that if I put MORE "stuff" on the bag, it would be improved. So I worked up a few crocheted flowers and sewed them onto the front. It is a very busy bag.
Here are some other businesses that offer newsletters and/or free patterns. I haven't read them all, so try them out and see if they are worthwhile. You can always cancel. If you're worried about your email being out there, sign up for a free Gmail address just for this purpose. You can check it, whenever, and see what interesting things you can make using available products or new products. Remember that whether talking about baking, crocheting, or painting--quality of products DOES matter. Try something out with less expensive alternatives, and if you like the results, spring for better quality materials in the next version.
